| Outline of Final Research Achievements |
Genetic abnormality of nerve adhesion molecule L1CAM causes one of the congenital hereditary nerve intractable disease L1 syndrome. In this study, to reveal molecular mechanism of neurological dysfunction due to L1CAM abnormality, we established iPS cells from patient-derived fibroblast cells. L1CAM abnormal iPS cells maintain pluripotency, and successfully differentiate into neural progenitor cells (iPS-NPCs). The biological characterization revealed L1CAM abnormal iPS-NPCs were decreased in terminal differentiation potential, and emerging neurons and glial cells have vulnerably low adhesion ability to matrices. Also it was found that cell migration ability was also reduced. Using the iPS cell technology, we succeeded in obtaining the materials to elucidate dysfunction mechanisms of the nervous system cells due to L1CAM abnormality.
